yes @cloudrunner04788 as @ragezapper has pointed you have to put the posts in the right category. it makes it easier for us to identify and test the solution on codeacademy but anywayshere is the difference between and list and dictionariesIn python lists by default have key that are their indices numbered from 0 to n-1 where n is the size of the list (you can use enumerate to control the indices) but if you don't want your keys to be just the default numbers but rather your own identifiers then you use dictionaries

For example

#imagine I have a list
random = ["Aardvark","Baa","Dab","Dab"]
#i can access an object with its index
print "The animal in this list is '%s'"%random[0]
#now I have a dictionary
random = {
"item 1":"Aardvark",
"item 2":"Baa",
"item 3":"Dab",
"item 4":"Carpet"
}
#i can access an object with its key
print "The animal in this list is '%s'"%random["item 1"]
